Scaffold shelf

Abstract

A removable shelf for attachment to a scaffold including a generally L-shaped frame releasably connectable around one of the vertically spaced horizontal crossbars of the scaffold. An object support panel is connected to one or both of the legs to support objects thereatop. Each leg is of sufficient length to extend between two vertically adjacent crossbars so that a distal portion of one leg contacts a lower one of the two crossbars to maintain the substantially horizontal orientation of the other leg and corresponding support panel when weighty objects are placed thereatop.

1. A removable shelf for attachment to a scaffold comprising:
 a generally L-shaped frame having an apex area and first and second legs and including a releasable engagement arrangement connectable around one of a plurality of vertically spaced horizontal crossbars of the scaffold to secure said apex area to the crossbar for substantially only pivotal movement of said frame on and about a longitudinal axis of the crossbar; 
 an object support panel connected to each of said first and second legs; 
 said first leg being of sufficient length to extend between two vertically adjacent crossbars wherein, when said apex area is releasably secured by said engagement member around an upper one of the two crossbars with said second leg and corresponding support panel being substantially horizontally disposed, a distal portion of said first leg contacts a lower one of the two crossbars to maintain the substantially horizontal orientation of said second leg and corresponding support panel when objects are, placed atop said support panel attached to said second leg; 
 said engagement arrangement including an elongated shaft held on said frame for sliding longitudinal translation of said shaft, said shaft having a U-shaped crossbar engaging member formed at one end of said shaft and a pull handle connected to another end of said shaft, said shaft being biased toward the upper crossbar to maintain said crossbar engaging member in a closed position against the upper crossbar. 
 
   
   
     2. A removable shelf as set forth in  claim 1 , wherein:
 said legs are oriented one to another at an angle slightly less than orthogonal to establish a true horizontal positioning of one said leg and corresponding said support panel. 
 
   
   
     3. A removable shelf for attachment to a scaffold comprising:
 a generally L-shaped frame having an apex area and first and second legs and including spaced apart releasable engagement members for connection around one of a plurality of vertically spaced horizontal crossbars of the scaffold to secure said apex area to the crossbar for substantially only pivotal movement of said frame on and about a longitudinal axis of the crossbar; 
 an object support panel connected to each of said first and second legs; 
 each of said legs having a length sufficient to span two vertically adjacent crossbars wherein, when said apex area is releasably secured by said engagement member around an upper one of the two crossbars with one said leg and corresponding support panel being substantially horizontally disposed, a distal portion of the other said leg contacts a lower one of the two crossbars to maintain the substantially horizontal orientation of said one leg and corresponding support panel when objects are placed atop said support panel attached to the other said leg; 
 said engagement arrangement including an elongated shaft dependently held on said frame for sliding longitudinal translation, said shaft having a U-shaped crossbar engaging member formed at one end of said shaft and a pull handle connected to another end of said shaft, said shaft being biased toward the upper crossbar to maintain said crossbar engaging member in a closed position against the upper crossbar. 
 
   
   
     4. A removable shelf as set forth in  claim 3 , wherein:
 said legs are oriented one to another at an angle slightly less than orthogonal to establish a true horizontal positioning of one said leg and corresponding said support panel. 
 
   
   
     5. A removable shelf for attachment to a scaffold comprising:
 a generally L-shaped frame having an apex area and first and second legs and including a releasable engagement arrangement connectable around one of a plurality of vertically spaced horizontal crossbars of the scaffold to secure said apex area to the crossbar for substantially only pivotal movement of said frame on and about a longitudinal axis of the crossbar between a first and a second position; 
 an object support panel connected to each of said first and second legs; 
 each of said legs being of sufficient and substantially identical length to extend between two vertically adjacent crossbars wherein, when said apex area is releasably secured by said engagement member around an upper one of the two crossbars and said frame is in the first position with said second leg and corresponding support panel being substantially horizontally disposed in a first lateral direction, a distal portion of said first leg contacts a lower one of the two crossbars to maintain the substantially horizontal orientation of said second leg and corresponding support panel when objects are placed atop said support panel attached to said second leg; 
 said frame being pivotable about the upper crossbar into the second position with said first leg and corresponding support panel being substantially horizontally disposed in a second lateral direction opposite from the first lateral direction, a distal portion of said second leg contacting a lower one of the two crossbars to maintain the substantially horizontal orientation of said first leg and corresponding support panel when objects are placed thereatop; said engagement arrangement includes an elongated shaft dependently held on said frame for sliding longitudinal translation of said shaft, said shaft having a U-shaped crossbar engaging member formed at one end of said shaft and a pull handle connected to another end of said shaft, said shaft being biased towards the upper crossbar to maintain said crossbar engaging member in a closed position against the upper crossbar. 
 
   
   
     6. A removable shelf as set forth in  claim 5 , wherein:
 said legs are oriented one to another at an angle slightly less than orthogonal to establish a true horizontal positioning of one said leg and corresponding said support panel.
